Innovating Pathology: PathChat and FDA Breakthrough

Dr. Faisal Mahmood, Associate Professor of Pathology at Brigham and Women’s Hospital and Harvard Medical School, joins hosts Raj Manrai and Andy Beam on NEJM AI Grand Rounds to explore the frontier of computational pathology. From pioneering foundational models for whole slide imaging to commercializing a multimodal generative AI copilot for pathology, Faisal shares how his team is redefining what’s possible in digital diagnostics. He discusses the power of open-source culture in accelerating innovation, his lab’s FDA breakthrough designation, and how generative AI could trigger widespread digitization in pathology. Faisal also reflects on his creative approach to problem selection and offers a vision for a future shaped by patient-level foundation models and agent-led computational biology.
